This breech-frame, and :l the barrels, having the rearextension 16 of the frame is formed with rpo 5o usual pivotalconnectionwith the frame lat an elongated slot 16 to receive the safety- 'thepoint 3. slide 16, adapted to be emtahlyoonneched so jecting portion 13of the bolt 12 extends `3o restore the gun to locked position, thebarwith the trigger, (not shown,) and said safetyslide has a connectionwith the oscillatory lboking-bolt, consisting of a rod 17,'support-A edbelow the rear extension 16 of the breech 5 frame by means ot adepending eye'l. A .coil-spring 18 surrounds the rod 17, one end bearingagainst the eye 17'* and the -opposite end agsinita nut 18, the latterbeing adj'nstable upon the rod to regulate the tension ro ot the spring.It will be seen that the rear end ofthe rod 17 bears against thesafetyslide 16, while its forward end -impingee against thelocking-bolt, thus insuring 'the movement of the slide when the bolt isoscil x5 lated.

The utility, operation, and functions of theV mechanism thus fardescribed will now beexplained.

When thegun is in locked position, the pro.-

.through'the opening in the barrel-lug, as shown inFigs; 1 and 2, and bymoving the lever laterally the b olt is oscillnted to release thebarrels and permit the gun to be z5 broken down. When the presen re uponthe,

spring 7 is thus released, the post is projected upward, bringing thebeveled shoulderG thereof in contact with the lip 1l* to lock the boltin its unlocked position. To

rels are tilted on the pivot 3, causing the lug 14 to strike the upperend of the pin 6, depressing said pin and the cylindrical post 5 andcompressing the spring 7. The bolt 1:. is thus released and is thenoscillated by means of the spring-actuated rod 17 engaging thebarrel-lug. The beveled surface of the shoulder 6 is held closelyagainst the lip l1l when the gun is in unlocked' position, and fo theupward force of the 'spring insures this close contact, thuscompensating for wear upon these coperating elements. Afurtherimportantfeatn re of my improved lconstruction is the eccentricsurface 12 of 5 the slot in the lockingbolt. lf this surface wereparallel with the opposite wall of the slot and concentric with thespindle, slight wear upon the surface 1S." would result in a looselocking connection. By inclining the surface 12 l, as shown anddescribed, and having the spindle inclined rearward aldownward and.nearward'lockiug strain is applied to the bar- :g1-1i .ig and wear uponthe bolt is compensated neces It will be obvious that the safety-slidewill be operated simultaneously with the m`ovement of the locking-boltthrough the rod 17.

I claimil. In a breechfioadingbreakdown hammerlees gun, the combinationwith the barrel-lug, of an oscillatory spindie supported in an inclinedposition within thc breech frame,- a lockinzbolt mounted on' saidspindle, a post to receive the impact of the barrel-lug, said posthaving an annular beveled shoulder, and a stop device carried by thespindle.

2. In a breech-loadin g breakdown hammerless gun, the combination withthe barrel-lug, of. an oscillatory spindle supported in au inclinedposition within the breeclurame', a locking-bolt mounted on the spindle,a post to receive the impact of the barrel comprising a hollow cylinderhaving a beveled shoulder,

' and a projecting pin, a bifurcated plug, with-v in the cylinder, aspring within the cylinder, and a stop device carried by the spindle. 3.In a bresch-load'in g breakdown hammerl les gun, the combination withthe 'harrelduml of an oscillatory spindle supported in an in clinedposition Within the breech-fratne, a locking-bolt mounted on thespindle, and constrncted to engage the barrel-lug, a yielding post toreceive the impact of the barrel-lug and formed with an annular beveledshoulder, a stop device carried by the spindle and adapted to engage thepost, a safetyslide and a connection between said slide and thelocking-bolt.

4. In a breech-loading breakdown gun, the combination with the stop-armcarried by the spindle of the locking-lever, of a spring-actuatedstop-post which is formed with au annular beveled shoulder at its pointof lockingcontact with the said stop-arm, so as to compensate for wear.
